  • -Accepting internships

    Connection with society

    We actively support innovation by dispatching our engineers to give technical lectures at technical colleges as part of a human resource development project sponsored by the Ministry of Education, Culture, Sports, Science and Technology, and to give technical lectures at committee meetings sponsored by incorporated bodies.

    We provide a place for blood donation on the plant premises, and our employees actively participate in blood donation activities. We hope that blood donation will contribute to the health of as many people as possible, and we will continue to cooperate with the Japanese Red Cross Society.

Human Resource Development

Human Resource Development

Through the introduction of our personnel system and educational programs such as various training programs, we are striving to improve our organizational strength to develop independent human resources who can think and act on their own and achieve high results.

  • Personnel system

    We have introduced a role-based grading system that sets grades according to each employee's position and size of his/her "role" required for the job. The system is based on the premise of "equal pay for equal roles" and allows employees to earn wages commensurate with the results of each role, regardless of age or career, with a high degree of difficulty and expectation.
    The role-based grading system will enable employees to be more independent in thinking about what they need to do to fulfill their roles and responsibilities, as well as to be able to respond flexibly to organizational changes through role definitions without being bound by fixed duties.

  • Examples of training

    -New employee training
    This training is held in April every year to improve the basic skills of new employees who are learning the basics of manufacturing.

    -Training for young employees and mid-career employees
    The program is designed to develop role awareness and basic skills in order to raise the speed of growth over three years: role awareness in the first year, critical thinking skills in the second year, and interpersonal skills in the third year.

    -Global human resources development training
    With the aim of developing human resources who can respond to the rapidly accelerating globalization, the employees will acquire a flexible mindset unconstrained by rules or procedures, language skills, communication skills, cross-cultural competence, initiative, proactivity, leadership, and expertise in their area of responsibility.

    -Action learning training
    We provide project-based training where participants learn to set up the company's issues, formulate solutions, implement them, and learn the methods and techniques for the implementation at the same time, with the assumption that they will actually implement them.

    -Personnel evaluation training
    Training is provided to managers and supervisors to improve the level of personnel evaluation and to ensure appropriate evaluation interviews.
